Answer

To answer the question "The spectrum of white light ranging from red to violet is called a continuous spectrum because," we can break down the explanation into clear steps.

### Step-by-Step Solution:

1. **Understanding White Light**:
- White light is composed of multiple colors. When passed through a prism, it disperses into a spectrum of colors.

2. **Identifying the Colors**:
- The visible spectrum of white light includes the colors red, orange, yellow, green, blue, indigo, and violet (often abbreviated as ROYGBIV).

3. **Continuous Spectrum Definition**:
- A continuous spectrum is characterized by the presence of all colors blending seamlessly into one another without any gaps.

4. **Color Merging**:
- In the case of white light, each color merges into the next. For example, violet merges into blue, blue into green, green into yellow, and so on.

5. **Conclusion**:
- Because the colors in the spectrum of white light transition smoothly from one to the next without distinct separations, it is referred to as a continuous spectrum.

### Final Answer:
The spectrum of white light ranging from red to violet is called a continuous spectrum because all the colors merge into each other without distinct separations, creating a smooth transition from one color to the next.
